SEWER TRAP.

UNITED NSTATES ATENT Genion.
HARRY o. STEWART, on HARRISBURG, PENNSYLVANIA.
SEWER-TRAP.
SPECIFICATION forming part of Letters Patent No. 274,149, dated March 20, 1883. Application filed September 25, 1882. (No model.)
To all whom 'it may concern:
Be it known that I, HARRY G.STEWART, a citizen of the United States, residing at Harxisburg, in the county ot' Dauphin and State of Pennsylvania, have invented certain new and'useful Improvements in Sewer Traps or Valves; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures or reference marked thereon, which form a part of this specication.
My invention relates to weighted valves, more especially adapted for use as sewer-valves, and it has for its object to construct the valve in such vmanner that a. water luting or seal may be obtained, besides the close joint of the `valve upon its seating, to prevent the escape ,of sewer-gases.
The invention consists essentially in the construction and combination of the valve and valve-seat plate, and their combinationwith a grating, substantially as hereinafter fully described, and as specifically pointed out in the claims. j
Figure 1 is a vertical section of so much of a man-hole as is necessary to illustrate my in ven. tion. Fig. 2 is an under side view of the valve and its seat-plate. Figs. 3 and l are top plan views of the same.
' [n the above figures of drawings like letters of reference indicate like parts wherever such may occur. f A indicates the masonry or the brick-'work ot' a man-hole, C, at the corner of a street, in
which is formed a recess, a, topermit the valve to open wide, and the weighted arms thereot| to assume the consequent vertical or nearly vertical position shown in dotted lines, Fig. 1.
B is the gutter that carries the water to the man-hole, and through itto the sewer,provided with the usual coveringplate and a grating, D, to arrest dbris, such as sticks ot' wood or othersolid substances thatmaychoke the valveopening or impair the functions of the valve.
`ln order that access may behad at any time to the valve, or through the valve to the sewer,
Ihinge said grate in the man-hole in such a mannerpas to be adapted to be swung to one side,
shown as tilted to one side.
E is the valve-plate, which plate may be d made square, polygonal, hexagonal, or ot'other angular shape; or it may be made cylindrical, and the valve-opening e may also be made of' any suitable forni. The upper face of the valve-plate may be made flat whenthe-masonry inV which itis set isiiush or practical-ly flush with the valve-opening. When, however, the plate is removably seated upon a supportingledge ot' thepmasonry, I prefer to make said face either concave or bow1-shaped, or incline the face from all sides toward the valve-opening e, as shown in Figs. 3 and 4.
The valve F is of such a shape as to correspond with the valve-openin g, and inthe drawings I have shown a rectangular valve hinged to the valve-plate so as to open downwardly. The seat e' for said valve may be made in any desired or usual manner to obtain a tight joint.
As shown in Fig. 1, the seat for the valve-is formed -by a projecting ledge, e2, that surrounds the valve, and in which it is seated. The seating may also be formed by means of a rubber packing, E', secured to the seat-plate E `by means of clamping-bars E2, between which and the seat-plate the rubber gasket is secured, as shown in Fig. 2. The valve has attached thereto or formed therewith one or more bent leverarms, F', carrying-a weight, W, made adjusta-V ble thereon by means of set-screws S, as shown. 'Itis evident that the pressure to trip the valve may be adjusted by means ot' said weights,
and consequently a sufcient volume ot' water may be always'maintained upon the valve to form a water lutin g or seal, whereby a valveclosure and water-luting are simultaneously obtainedto prevent the escape ot sewer-gases into the street or house or other place where such valve is located. By forming the valveseat plate bowl-shaped or inclined toward the valve-opening such substances as sand or others not retained by the grating' are more readily washed out than if the upper face ot' the seat-plate were flat.
From the above description and by an inf spection of the drawings the operation of the valve will be readily understoodil by all those conversant with this branch of the arts, `and y needs therefore no further description.
IOO
Although I have described and shown the l structed and arranged for co-operation subapplication of a valve to a man-hole of a streetsewer, it is obvious that said valve may be applied to any other sewer-connection or waterdischarge, such as sinks or sewer-traps.- It
is also obvious that no Water can back out ot" the sewer-connection, since the greater the pressure of the Water backing up from the sewer the tighter will the valve be held to its seat.
Having now described my invention, what I claim is l. In a sewer or other valve, the combination, with the valve-casing or masonry and a downwardly-opening valve held to its seat by adjustable weights, of a valve-seat plate hav-- ing an outwardly-flaring valve-port, all oonstantially as and for the purposes specified.
2. In a sewer-valve, tbe combination, with the valve-casing or masonry and a downwardly-openng valve held to its seat by adjustable Weights, of a seat-plate having an outwardlyflaring valve-port and. the superposed grating D, all constructed and arranged for co-operation substantially as and for the purposes specied.
In testimony whereof I afx my signature in presence of two witnesses.
